Application filed J'anuary 2a, 1928. Serial a... 248,641.

This invention relates to an automatic bookkeeping machine. It primarily concerns improvements in automatic bookkeeping machines of the type having a paper carriage which is automatically tabulated back and i A forth across the machine, stopped in various columnar positions in which positions diiferent calculating or bookkeeping functions are performed, and the results printed upon the paper in the carriage.

These. machines are sometimes provided with a plurality of counters comprising, in the Burroughs machine, an upper counter which is capable of both addition and subtraction and a plurality of lower counters any one ofwhich may be shifted into position to add items and from which a total and a subtotal may be taken. Separate controlling devices are provided for the upper and the W) lower counters which must be manually manipulated in the appropriate manner in the different columnar positions of the carriage 1n order to secure the desired calculating func-' tions in those positions. The manipulation of these controls'is fairly confusing to anlnexperienced operator and requires time whereas it is desireclto have the operations performed as uicklyas possible and without the needfor hig lyexperienced operators. The present invention is directed to overcoming these difficulties by making certain of the operations automatic, particularly totaling and subtotaling from the lower multiple counters and sub-totaling from the upper counter.

' The general object of the invention is to provide an improved automatic controlling mechanism for bookkeeping machines, par- 'ticularly a mechanism for automatically taking a total or sub-total from any one of a plurality of counters.

Other objects and advantages of the vention will hereinafter appear. An embodiment of the invention is shown 3 in the accompanying drawings in which:

The invention is shown applied to a Burroughs calculating machine, the general features of which are known in the art so that only a brief description will be given here.

General construction with which the pinions of an upper counter 916 cooperate. This counter is rocked into and out of engagement with the racks by a pitman 914 connected to an oscillating arm 913 having studs 961 and 961 engaged by the pass-by pawl 821 on the oscillating arm 813. The pitman 914 is positioned by the total key 265 which moves the link 911 to position the pitman so that its forward branched end will engage either the stud 958 or the stud 958 on the frame 910 carrying the counter 916.

\ A carriage C is provided which is automatically tabulated back and forth by mechanism described in detail in Rinsche Patent No. 1,580,534, to which reference is made.

The invention is shown applied to a multiple counter machine, but it is not necessary to understand all the details of the multiple counter mechanism in order to understand the present invention and, therefore, only a brief general description will be given- The multiple counters (Fig. 2) are automatically selected for cooperation with the actuators by means of the paper carriage C which carries a cam bar 111 operating on a roller 112 on the end of an arm 113 of a pivoted yoke 114 whose other arm 115 is connected to a spring 116 which, in turn, is connected to a lever 117 pivoted on the shaft 118. The lower end 119 of the lever 117 bears against a roller stud carried by an arm 120 fixed to a shaft 121 that is urged clockwise, as

. viewed in Fig. 2, by a spring 122. Fixed to the other end of the shaft 121 is an arm 123 having a universal joint connection with an adjustable clamp 124 carried by the shaft 125 on which the multiple counter pinions 110 are mounted. It will be clear that by rocking the shaft'121 the multiple counters will be shifted longitudinally toposition different ones of them for coaction with the actuator racks. The cam bar 111 on the paper carriage has cam surfaces of different depths at selected points for selecting the desired counter in predetermined positions of the carriage. A locking mechanism designated generally as'126-127 is provided for bolding the selected counter in position after it has been set.

The selected counter is rocked into and out of engagement with the actuator racks by 'means of a cam having a plurality of cam projections for engagement with rollers 131 carried by a yoke 132 that is slidable to different positions on the shaft 133, but which, when rocked by the cam 130, rocks the counter frame. By sliding the yoke to different positions on the shaft 133, the timing of the engagement and disengagement of the counters with the racks may be varied. The yoke is moved to its different positions on shaft 133 by means of a bell crank 134 one arm of which is connected to the yoke 132 and the other arm of which is connected to the lever is positioned to cause the selected counter to be rocked into engagement with the racks in the proper manner to take a total. When the lever 104 is pushed back to the Fig. 5 position, the parts are conditioned to cause a sub-total to be taken. In the actual takin of both the total and the sub-total the actuator racks must be released and, for this purpose, the usual total key 265, is employed, which, when depressed, releases all the racks. However, this key also normally controls the rocking of the upper counter into and out of engagement with the racks in the taking of a total anda sub-total on the upper counter. It is undesirable to have the upper counter conditioned for taking a total during the taking of a total or sub-total from one of the lower counters. Accordingly, arrangements are made such that when the controls for the lower counters are conditioned for the taking of a total or sub-total the conbackward from its central position shown in Fig. 1. The other arm of the bell crank lever is pivoted at 143 to a link 144 which :11.-

extends to the front of the machine where it is provided with a lateral lug 145 on its front end positioned to engage the link 911. The link 911 normally occupies the position illustrated in Fig. 1, but whenever the control 3 lever 104 is moved from normal, the link 911 is moved forward through the connections above described to ition the long slot 146 in the upper end of tlie link under the stud 147 on the stem or lever operated by the total key 265. When the link is so positioned, depression of the total key will not move the link downward and such depression will not,

therefore, set the controls for the upper counter to take a total or sub-total from it. Depression of said key will, however, release the actuator racks in the usual manner to permit the taking of a total or sub-total from the selected lower counter.

The machine also embodies a cycling mechanism for automatically depressing the total key 265 in certain columnar positions of the carriage, such mechanism being disclosed in the co-pending application of Robert L. Muller, Serial No. 78,028 filed December 25,1925, but, here again, it is not necessary to understand the details of said mechanism in order to gain an understanding of the present invention, it being sufiicient to know that the total key 265 is automatically depressed certain columnar positions of the carriage.

Automatic sub-total from lower multiple counter pose the carriage is provided with a control shaft on which is splined a square sleeve 11 that is held in place by a set screw 12 illustrated in Fig. 11. The sleeve 11 carries a stud 13 on which is mounted a roller 14 in alignment with the arm 15 of a yoke-shaped controlling member16 (Figs. 3 and 4) pivoted on the shaft 17 supported in the back panel 18 of the machine and in a bracket 19 projectin from'the machine frame. The yokeshapeg control member 16 has an inner arm 20 extending from it in the opposite direction to-the arm 15 which arm has a bifurcated end straddling the arm 21 of a four-armedlever pivoted at 22. The four-armed lever is normally urged in a counter-clockwise direction by a spring 23 one end of which isconnectcd to the upper arm 24 of said lever and the other end to a machine stud. This spring serves to urgethe parts toward normal position and to position the yoke-shaped controlling member 16 so that its arm 15 is up in the path of the roller 14. The lower arm 25 of the fourarmed lever is connected to one end of 1 a spring 26 whose other end is connected to a downwardly extending arm 27 of a threearmed lever which is pivoted at 28 to the forwardly extending arm 29 of the four-armed lever. The spring 26 normally urges the three-armed lever in a clockwise direction, the

movement of said lever relative to the fourarmed lever being limited by engagement of the inwardly extending lug 30 on thereab wardly extending arm of the three-armed lever with the underside of the forwardly extending arm 29 of the four-armedlever.

The forwardly extending arm 31 of the threearmed lever is pivoted to a link 32 whose lower end has a shoulder 33 normally engaging I a stud 34 (Fig. 3) of. a bell-crank lever 35,

and 4) having a notch in one of its ends en-- pivoted at 36 to a stud on the machine frame 1 (see Fig. 3). The other arm 37 of the bellcrank lever has a bifurcated end which straddles a stud 38 on the lever 102 that controls the mechanism for conditioning the I lower counters for thetaking of a total or a sub-total. p

The control lever 104 is normally locked in its neutral position by a latch 40 (Figs. 3

' 1 gaging'over a stud 41- carried by the lever.

The other endof the latch 40 carries a stud 42 engaging in a notch in the upper end of a link 43 which is normally ur e upward by a spring 44. The movement 0 link 43 is limited by the length of the slots 45 in it which engage over studs 46 carried by the machine frame. The latch is released at each operation of the machine by means of the sector 813 which is rocked counter clockwise as viewed in Fig. 3 during the forward stroke and returned during the rearward stroke of the machine. This sector carries a stud 47 engaging over the hooked nose of a pass-by pawl 48 pivoted at 49 to the end of the link 43. The pawl is urged clockwise by a spring 50, but is limited in its movement in this direction by the engagement of the lateral lug 51 on the pawl with the edge of the link 43.

The operation of the parts thus far described is as follows:

Whenthe paper carriage tabulates to the column where a sub-total is to be taken from the lower counter, the roller 14 depresses the arm 15 which raises the arm 20 and rocks the four-armed lever 21-242529 clockwise. This moves the three-armed lever 27-31 downwardly, but the forward arm 31 which is pivoted to the link 32 cannot move downward bodily because the link 32 is blocked against movement through its connections to the control lever 104 which is locked by the latch 40. Accordingly, the three-armed lever 2731 is rocked counter clockwise about its pivot on the link 32 and this tensions the spring 26 which stores power forsubsequent operation of the parts. Prior to taking a sub-total from the lowercounter, the machine is 'ven a spacing stroke as is usual in Burroughs machines, after which it is given a stroke of operation for the taking of the sub-total, all of said strokes being given the machine automatically by the cycling mechanism hereinbefore referred to. The present invention will operate equally as well if the machine is operated by hand. At the beginning of the spacing stroke the stud 47 on the arm 813 acts on the'pawl 48 and moves the link 43 down wardly which raises the latch 40 and unlocks lever 273 1.clockwise to lowerthe link and rock the bell-crank lever 35 counter clockwise which results in swinging the control lever 104 rearwardly or counterclockwise to a sub-total position (Fig. 5). The selected lower counter is thus automatically conditioned for the taking of a sub-total. Upon the next stroke of the machine the total key 265 is antomatically depressed and the sub-total is taken. Depression of the total key will not' affect the controls for-the upper counter, because as' previously explained, the positioning of the lever 104 for a sub-total from the lower counter. automatically disables the connections between the total key and the upper counter controls.

The parts return to normal position in the followlng manner: After the sub-total is taken the carriage tabulates to its next columnar position, thereby releasing the arm 15 and permitting the spring 23 to move the four-armed lever 21-24-2529 back to normal which raises the link 32 and frees the bellcrank 35. The control lever 104 together with the lever 102 is urged to central posltion by the centering means illustrated in Fi 4 comprising two bell-c-rank levers 52 an 53 pivoted at 54 and having their rearwardly extend ing arms ur ed toward one another by the spring 55. hese arms straddle a stud 56 on the projecting arm 57 of the control lever 104 and a limit stud 58 on the machine frame. It will be readily understood that whenever the control lever 104 is moved either forward or backward from the position of Fig. 4, one

- of the bell-crank levers is moved with it while the other is held against movement by the machine stud 58. This places a tension on spring tending to rock the moved bellcrank back to normal to release the lever 104 to its central position. The spring 44 raises the link 43 to move the latch 40 back to locking position to hold the lever 104 in its central position. r

Automatic total from lower multiple counter When a total is to be taken from the lower counter the control member 104 must be moved forward to the position illustrated in Fig. 7. This calls for moving the lever in more 'tioned so that it will act on a lever 61 slightly the opposite direction to which it was moved in the sub-totaling operation and this is accomplished by mechanism as follows:

Referring to Fig. 6, the carriage control rod 10 is provided with a cam 60'illustrated in detail in Fig. 10.. This cam is posibefore a second roller 14, exactly like the first roller 14hereinbefore described, acts on the arm 15. The arm 61 is an integral part of a yoke 62 (Fig. 1) pivoted on the shaft 17 and provided with an arm 63 extending in the opposite direction and having a bifurcated end straddling a stud 64 on an arm 65 (Fig. 3) pivoted to the back panel 18 of the machine. The arm 65 has a lateral lug 66 extending under one end of a pivoted arm 67 having an abutment 68 engaging one arm 69 of a three-armed lever which has two other arms 70 and 71 and which is urged in aclockwise direction by a spring 72. The arm 69 carries a stud 73 operating in a slot 74 in a link 75 pivoted to theupper end of the link 32. One end of a spring 76 is connected to the stud 73 and the other end to a laterally p ll'pjecting lug 77 on the end of the link 75.

e upper end of the link 32 is provided with a T-shaped slot 78 in which operates astud 79 earned by an arm 80 which is integral with the lever 102. In the sub-totaling operation heretofore described, the link 32 was free to move vertically owing to the fact that the stud 79 was positioned'in the vertical part of the slot 78 but, in the totaling operation, the link 32 is moved by lever 67 and link 75 so that the horizontal part of the T-shaped slot 78 moves over the stud 7 9 thereby locking the link 32 with the arm 80. The operation is as follows:

The normal position of the parts is illustrated in Fig. 1 where it will be observed that the stud 79 is in front of the horizontal portion of the slot 78. As the carriage tabulates to the columnar position where a total is to be taken from the lower counter, the cam 60 operates prior to the roller 14 and depresses the arm 61 which rocks the lever 67 clockwise thereby rocking the three-armed lever 69- 7 07 1 counter-clockwise and, through the spring 76, moving the link 75 forward to rock the link 32 clockwise on its pivot to the arm 31 to position the horizontal part of the slot 78 over the stud 79. This also moves the shoulder 33 out of the path of the stud 34 on the arm of the bell crank lever 35. The link 32 is thus freed of the bell crank lever 35, but it is connected with the arm 80 integral with the control lever 102.

As the carriage reaches its total column the roller 14 acts on the arm 15 and tensions the spring 26 in the same manner as was previously described for sub-totaling. In the taking of atotal the machine is given a spacing stroke followed by a totaling stroke for taking the total. At the beginning of the spacing stroke the stud 47 acts on the pawl key 265 is automatically depressed and a total is taken from the lower counter. Depression of the total key does not affect the upper counter controls for reasons already given.

After the total is taken the parts move back to normal position under the influence of the springs controlling them as previously described. The spring 72 rocks the three- ;armed lever 697071 clockwise back to normal and the stud 73 en aging in the end of slot 74 carries the link 5 rearward thereby rocking the link 32 back to its normal posi tion and moving it so that the stud 79 is in the vertical portion of the slot 7 8. The clockwisev movement of the three-armed lever 69--70-71 also restores the arm 67 with its connections and the yoke 62 back to'normal.

The parts 104, 102 and ,80 are restored to normal under the influence of the spring pressed arms 52 and 53.

Automatic sub-total from upper counter When a sub-total is taken from the upper counter the control lever 104 should remain in neutral position, because the parts associated therewith do not control the taking of a sub-total from the upper counter." Instead, said sub-total is controlled through the usual total key and the pitman 914 that rocks the upper counter into and out of engagement with the rack. Accordingly, in the columnar the machine is operated, but since there is no force exerted to move the control level- 104 the same will remain in central position where it is normally held by the arms 52- 53.' The latch releases and restores idlydurlng the operation.

The control bar 10 on the paper carriage has a cam (Figs. 8 and 9) for operating on the arm 61 when the carriage is in its columnar position for taking a sub-total on the uppercounter. It will be noted that there is no roller 14 adjacent the cam 90 and that the cam 90 does not have the long tail of cam 60 and hence there is nothing to operate on the arm 15 when the carriage is in the columnar position specified.

When the. carriage reaches its column for a sub-total on the upper counter, the cam 90 0 depressesthe 'arm 61 which results in rocking the lever 67 clockwise,'thereby rocking the three-armed lever 69 7071 counter clockwise and pushing the link 7 5 forward to move the link 32. The movement of the links 75 and 32 hasno effect in the operation of the mechanismbein merely an idle movement as there is'nothmg to move the link 32 vertically for reasons already explained., However, the counter-cloc wise movement of the three-armed lever 69.70-- 71 positions the outer end 91 of the arm 7 0 so as to interfere with thepass-by pawl 821 on the arm 813. to effect the taking of a subtotal 'on the upper counter in the following manner: I I

When the machine is in the sub-total column it is given a spacing stroke followed by the sub-total-taking operation, such operations taking'place automatically under the control of the cycling mechanism referred to. At the beginnin of the forward portion of the spacing stro e the pass-by pawl 821 engages. the stud 961! on the lever 913 and rocks the latter counter-clockwise thereby moving the pitman. 914 forwardly and rocking the counter frame to move the counter out of engagement with the actuator racks, the pitman being at that time, in engagement with the stud 958 on the counter frame. The counter remains out of engagement with the racks until near the end of the forward stroke when a link 93, Whose forward end is pivoted to the counter frame at 94 and whose rear end is provided with a shoulder 95, is engaged by a stud 96 on the member 813 which draws the link rearwardly and rocks the counter into engagement'with the racks. Normally, the pass-by pawl 821 would engage the stud 961 of the member 913 at the beginning of the return stroke, but on account of the pawl 821 being provided with a stud 92 which engages the end 91 of the arm 70, the pass-by pawl is held out of the position where it can engage the stud 961 and it is therefore inactive to rock the member 913 clockwise. In this way, the counter 916 is rocked out of engagement at the beginning of the spacing stroke and is then rocked into engage- 1 ment with the racks at the end of the forward part of the spacing stroke by means of the link 93. The condition of the parts is changed for the sub-totaling stroke owing to the fact that the total key 265 is automatically depressed prior to the beginnin of this stroke. Depression of the total fie the pitman 914 downwardly and although the pass-by pawl 821 acts on the stud 961*and rocks the member 913 counter-clockwise to move the pitman 914 forwardly, said pitman has .no action in rocking the counter frame to move the counter out of engagement withthe rack because the forward branched end of the pitman 914 is not in engagement with the stud 958 but is in a position to engage the stud 958 to rock the counter into engagement with the racks which action would take place except for the fact that the counter is already in engagement with the racks and such movement is not necessary. Depression of the total-key causes a stud 97 to engage and move the link 93 downwardly so that its shoulder is out of the path of the stud 96 and hence, at the end of the forward part of the sub-totaling stroke, the link 93' does not act to rock the counter. of the return stroke, the pass-by pawl 821 does not act on the stud 961 because the pawl is held disabled by the end 91 of the arm 70. Accordingly there is nothing to rock the member 913 clockwise to push the pitman 914 rear'wardly with the result that the counter remains in engagement with the actuator racks for, a sub-totaling operation.

During the first part of the next operation,

y moves At the beginning the carriage tabulates to the next columnar parts'to normal position, the pitman 914 be- 1ng returned a slight distance rearwardly by the usual spring shown, for example, as the spring 108 in Muller Patent No. 1,397,774.

Automatic transfer of totals and sub-totals The machine illustrated also has provisions for automatically transferring to the upper counter the sub-totals and the totals taken on the lower counter. I

When the total key 265 is automatically depressed to take a sub-total from the lower counter, the link 911 is not lowered, as already ex lained. However, the normal condition o the upper counter controls is such that addition occurs in the upper counter.

This normal condition is not disturbed and hence the sub-total taken on the lower count-er adds into the upper counter in the following manner:

At the beginning of the forward stroke the lever 813 is rocked counter-clockwise and the pass-by pawl 821 strikes the stud 961 to rock the lever 913 counter-clockwise to move the pitman 914 forward. At that time the upper branch of the pitman engages the the lever 813 moves clockwise and the pass-by" pawl 821 would engage the stud 961 to rock the lever 913 clockwise to pull the pitman 914 rearward and rock the counter into vengagement with the racks, were it not for the fact that the counter is already in engagement with the racks and such action is not necessary. The upper counter remains in engagement with the racks during their return to normal and hence the sub-total on the selected lower counter is added into the upper counter. p

The same transfer action takes place during the taking of a total from a selected lower counter. The controls for the upper counter remain in addition condition, the upper counter is rocked into engagement with the racks at the end of the forward stroke and remains in engagement during their ascent with the result that the total from the selected lower counter is transferred to the upper counter.

'Manual control of lower counter shown in Muller Patent No. 1,397,774, par- ;ticular Fig. 17 thereof. when this key is depressed a pivoted arm shown in Fig. 3 of the present application and the equivalent of the arm 87 in the aforesaid Muller patent is rocked clockwise against a stud on a link 106 pivoted at its forward end to thesubtraction lever 107. The link 106 carries a stud 108, which, when the link is moved downwardly, engages the inwardly projecting lip 109 on the link 43 thereby moving the latter downward and releasing the latch 40. This releases the control lever 104 for manual manipulation.

From the above it will be seen that the machine is automatically conditioned in predetermined columnar positions for the taking of a sub-total on any one of the selected counters of the lower multiple counter, for the taking of a total from a selected lower counter, or for the taking of a sub-total from the upper counter. This avoids the necessity of the operator manipulating the controls and makes the machine automatic.
